20`Claims.

My. invention relates generally to. fountain pens and moreparticularly to the class of fountain pens having a quick opening closure or housing for the pen nib.

It is often desirable, as when holding papers in one hand, to be able to open a fountain pen with a simple pushing motion of the ngers of the other hand, insteado-f havngto use both hands to unscrew a cap from the body of the pen. When the penY isto be closed, it is important thatl the closure be tight, to prevent leakage of ink.` It is also desirable, both for economy in manufacture .and for convenience, lightness, and durability, to construct the carrying and covering portions of the pen holderwith as few parts as possible, vcombining the functions of necessary parts and also some oftheir structural weight and strength whenever opportunity is presented.

It is therefore a principal object of my invention to. provide a pen having a quick-actingiclosure easily operable with one hand.

Itis a further object to provide a closure which will be automatically tightened and sealed by the simple act of clipping the pen to the users clothes.

Another object of my invention is to provide a pen having few small frangible parts or parts subjected to bending stresses and tensions, and to utilize the strength of the major partsiof'my pen to effect opening and closing and'holding in those positions.

Still another object is to combine the functions of the remaining major parts of -my lpen in such a manner that a few operating parts may be sturdily constructed, and materials and manufacturing cost be saved on the others.

In attaining these objectives, as will presently be .made clear from the detailed description which follows and from the drawings, I have considered the principal, or most fundamental, parts of a fountain pen to be the nib, a barrel supporting rthenilo and serving as lhandle and vink reservoir, a closure protecting the nib when it is not in use, and a clip for conveniently carrying thepen. In myvpenthe nib may be conventional, though not necessarily so. The barrel isl also conventional in its functions of pen-holder, handle, and ink reservoir .and is changed inY detail to enable itftovsupport slidably a cap sleeve and to bring pressure against a movable4 segment of the cap sleeve. The cap .sleeve is tapered to a Ablunt point at the nib end and the movable segment extends forwardly to the point and is hinged rearwardly thereof.' Forward pressure "of kthe `Vbarrel'witl'lin'-the sleeve moves the segment outlll vwardly :and permit-sA thenib `to emerge from the closure. In myn-referred embodiment, the segment is held closedywhen the pen is'notin use, by yazspri'ng Aacting Aagainst arearward extension of the segment beyond the hinge. In a modified embodiment, 'a different type of spring urges the barrel rearwardly within the cap sleeve and holds the segment. closedwith a trigger action Vvwhich is released whenv the v'barrel ispushed forward. In all my embodiments; the rearward extension of the segment, `pushed outwardly from the cap sleeve'when the segment is closed, serves as'the clip, and the., action of jamming the clip on the edge" of a pocket serves to tighten the closure. As the tapered cap-sleeve isfco-mparable to the ordinary threaded' cap and the hingedsegment.

isA integral withfthe clip, I have provided a pen openable-and closable 'with onef'handA by modificationofl three of the vfour fundamentals land the `addition of a spring.

Further advantagestwillappear from consideration of-the followingd-etailed description, and

vof a` modified form ofjmy invention, the outer f parts` being shownl in `section 1an-d` the inner parts Figure 10 is a similar view of the modification shown in Fig. 9 buI-I with the pen in open position. Turning now to Figs. 1 to 5, illustrative of my preferred form, I2 indicates the barrel of my pen, forming the conventional ink reservoir, and carrying a nib I3 mounted in the usual manner so as to have its point eccentric from and, when in normal writing position, above the longitudinal axis of the pen. .A cap sleeve I4; tapered at its forward end to form a bluntly pointed cap, is carried'slidably on the forward end of the barrel I2 and extends rearwardly to cover that portion of the barrel ordinarily grasped by a writers fingers. The cap sleeve I4 has a slot extending longitudinally from the tapered forward Vend to a point slightly rearwardly of the beginning of `the taper, and this slot is fitted with a closure or segment I5 carried by a hinge pin I6 mounted on the cap-sleeve at the rearward end Vof the slot. The closure I5 ts iush `with the pointed end of the cap sleeve Ill and gives the appearance of being simply a longitudinal segment cut therefrom and replaced on a concealed hinge.

A prolongation of the closure I5 extends rearwardly of the hinge pin I6.to form a clip I'I, terminating in the usual clip button I8, the closure and the clip being. integral in one member and making a slight angle with each other at the hinge pin I6 so that when one lies flush with the cap sleeve, the other will extend outwardly therefrom. Thaty portion ofthe cap sleeve lying directlyunder the clip I'I has on its inner side a longitudinal ridge I9 terminating in a hump or protuberance 2i) formed by an inward curvature of the cap sleeve and thereby forming on the outer Y side of the capsleeve a groove |90, and a recess whenthe closure I5 is open and the pen is ready, for writing. A leaf spring 2|, .mounted in the groove |911 urges the clip I'I outwardly.

The barrel I2 i-lts slidably within the cap sleeve Id for a sufficient distance to create a bearing surface and then has a portion 22 of reduced diameter bearing against the ridge I9. An elongated recess 23 is provided to receive the protuberance 20, the forward and rearward ends of the recess 23 cooperating with the protuberance 20 as stops limiting the movement of the cap sleeve I4 upon the barrel I2. The barrel extends forwardly of the reduced portion 22 .in a portion 24 of further reduced diameter to accommodate the inward curvature of the journals for the hinge pin I5. To permit assembly of the cap sleeve upon the barrel a helical groove 25 is provided in the portion 22 communicating with the recess 23. When the cap sleeve is placed upon the barrel, the protuberance 20 slides over the reduced portion 24, passes along the helical groove 25 and enters the recess 23, a leaf spring 26, shown in Fig. 5, permitting itvto enter but blocking its egress except under pressure, It will be seen from Fig. 5 that the recess 23, acting as a guide for the protuberanceZ, prevents rotation of the cap lsleeve upon thebarrel of the pen and keeps the closure I5 in alignment with the nib I3.'

The forward end ofthe barrel I2 projects beyond the mounting of the nib I3 to form a nibguard 2l with anYup-turned nose 28 which does not quite make contact with the closure I5 when the cap sleeve I4 is pushed forward and the .closure is closed, but does not make'contactv with it and pushes it outwardly when the cap sleeve is retracted, protecting the point of ther nib at all times from contact `with the closure. The

2,416,112 ffl '.1

side edges of the closure I5 are preferably covered' with a thin resilient gasketing material, as indicated by dotted surfacing at 29 in Fig. 3, and the closed position of the closure is limited by Contact of this gasket with the sides of the slot in which the closure rests, rather than by contact of the closure with the nose 28.

To place the pen in operating position, the writer may graspthe cap sleeve between the middle finger and thumb and push with the index nger against the rearward end of the barrel. The nose 28 will be pushed against the closure I 5, causing it to open against the resistance of the spring 2| and allowing the nib to emerge.

`The clip Il falls into the groove |9a in flush alignment with the cap sleeve, and the clip button I8 falls into the recess 20a. The' protuberance 25, in turn, by contact with the end of the recess 23, limits the exposure of the nib to the amount required for writing. The nose 28 continues in contact with the tip of the closure I5, and thereby keeps the spring 2| under tension. As this tension acts transversely to the axisof the pen, it does not urge the cap sleeve forward again, but rather, by pressing on the extreme forward member of the barrel, it urges misalignment of the barrel and the cap sleeve, creating added friction 'between them to hold the cap sleeve in place. When the pen is to be closed, the barrel may be grasped between the fingers and palm, and the cap sleeve urged forward with the thumb and indexrnger. When the pen is clipped to' the writers pocket, the pressure beneath 'the clip I1 adds to the pressure of the spring 2| to press the .gasketed closure I5 into its slot with a leak-proof seal. It will be observed that the pen may be opened and used without looking at it, as the clip is aligned above the nib and indicates to the writers fingers when the nib is held in position for writing.

In Figs. 6, 7, and 8, I have illustrated a modied form of'my pen in which no helical groove 25 is necessary.. The first reduction in diameter of the barrel I2 is also eliminated and the barrel is in sliding contact with the cap sleeve III Y until the reduced portion 24 is reached. A long groove 35, having the depth of the protuberance 20 is substituted for the recess 23 and is continued forwardly to the reduced portion 2lI,Y so

that the cap sleeve I4 may be assembled on the barrel without the half-twist u'sed in assembling my preferred form. To prevent the cap sleeve from being detached from the barrel, the upturned nose of the nib guard 2l is provided with a catch 3|,` and the closure I5 is provided with a detent 32 which engages the catch 3| when the Vclosure is closed. If it is desired to remove the rel I2 has a portion 35 of reduced diameter ex-l tending forwardly from a shoulder 36 near the joint of the cap sleeve I4 and the sleeve extension 33, and terminating in a conical point 3l, bearing the stylus point 38. The conical point 3'I is ringed by an annular groove 39 having a sharp rearward facing shoulder and a sloping forward facing shoulder, vthe rearward facing shoulder corresponding in function to the catch 3| of the previously described modification.

The cap sleeve 'f 1M has anf interir-'lannular ridge i 40,'"1bel2 agrarias tween which and the shoulder'36 vthereis a spring: '1

the groove 39 andv holds the pen open. Because of the axial alignment of the stylus point 38, it

is not necessaryto key the cap sleeve Is against rotary motion relative tothe barrel I2, and the reduced portion is not provided with a groovev to receive the ridge `I9 and the protuberance` 29 of the cap sleeve but is sulciently reduced in di-r ameter so thatthe groove I da and recess 20a t maybe a little deeper than is neces'sarytobring' theclipollinto ush alignment with the capv sleeve when the pen is open. This added depth permits the writerto press the clip inwardly' and to disengage the point ofthe closure I5 v from-the groove 39in order to' close the pen.V
